Secondary Electron Emission Characteristics of Epoxy Resins with Nano-silica Addition and Thermal Treatment

Abstract

With the activation of the lunar manned exploration plan, a power device that can be driven with high efficiency is required for effective utilization of electric power resources. On the ground, the development of nanocomposite materials in which nano-sized fillers are added to epoxy resin is being developed for semiconductor encapsulation materials and inverter module cases. These materials are expected to be applied to the development of lunar rover, and further improvement of the dielectric strength of the materials is required. Therefore, this time, we focused on the secondary electron emission yield (SEEY), which is the electrical property value, and measured for the nano-silica added epoxy resin when it was subjected to high temperature treatment, and whether it could be applied to a semi-empirical model formula. We report on the fact that we have examined the above.
